Consider

the variable declaration:                                                                            

         int x = 5;

     Which

is a valid declaration of allowing the variable

Assuming an array declaration, int num[5], how will num be passed to a function?

   int x=12, y=3;

        ptr1=&x; ptr2=&y;

        *ptr1 = (*ptr1)* (*ptr2);    

         y+=2;

        printf("%d %d",*ptr2,*ptr1);

Array subscripts ranges from 0 to n(array size)

The *

indirection

operator is used to return the address of the operand that follows.

The three

values that can be used to assign to a pointer are: NULL, memory address or 1.
